COMPOUND TRACK-RAIL.

struction comprising a plurality of assembled members firmly united to each other, but easily separable from eachother whenever necessary; to provide a detachable railtread adapted to be attached on rails already in use, to strengthen the rails and prolong the life of the rails; to provide in conjunction with a series of rail bodies in line with each other, and a corresponding series of detachable rail treads simple and effective means for holding the treads firmly on the rail bodies and preventinglifting of the abutting ends of the rail treads; to provide attaching plates of'improved form and to provide other features of construction as will hereinafter appear.

The invention is illustrated in the accompanying drawing to which reference is hereby made and will now be described in detail and the novel features thereof will be recited in the claim. 7

The invention comprising the rail as a whole and including a detachable tread and connecting devices will first be described. But the detachable tread and the attaching devices are applicable to worn rails already in use as shown and will be described later.

Figure 1 is a side elevation of a complete rail embodying my invention; Fig. 2 is a vertical transverse section on the line 2-2 of Fig. 1. Fig. 3 is a side elevation of a rail of usual construction equipped with a detachable tread and attaching plates of slightly modified construction, embodying my invention. Fig. 4 is a vertical trans verse section on the line 44 of Fig. 3, and Fig. 5 is a diagrammatic top plan of, two compound track-rails embodying my invention, showing how the detachable treads break joints with the bodies of the rails to] which they are attached. The same reference numerals designate the same parts In all the views.

Specification of Letters Patent.

' Application filed June 2, 1921. Serial No. 474,455.

The complete rail structure will preferablybe of rolled steel.

The railbody comprises a base 6, a webmember 7 and a longitudinal flange 8. The member 7 has holes 9 to receive bolts 10 connecting the members of the rail. The member 7 preferably hasa flat top 12. I

The-tread 13 comprises adownwardly ex tended member 14 having a hole 15 accom modating one of the bolts 10, and a downwardly turned member 16 having a longitudinal rib 17 and a longitudinal channel 18 accommodating the member 8 of the rail body and also accommodating the flange 19 of the attaching plate 20.

Each attaching plate 20 has a series of holes 21 accommodating the bolts 10.

When the parts are assembled the bolts ,10 will extend through the holes 15, 9 and 21 and nuts 22 on the bolts will securethe assembled parts.

An attaching plate 23 has a shoulder 24 on which the member 14 rests and has holes 25 to receive the bolts 10. When the parts are assembled the upper member of the plate 23 will bear against the member 14 of the tread 13 and the lower part of the plate will plates 20 except as tolength and the plates 23 are similar to the length. From the foregoing description, it is obvious that when the parts are assembled as described, the shoulder 24 and the flat upper surface 12 of the web 7, will securely support the tread 13 and the members 8, 19 and 17 will co-act to prevent any lifting of the tread-members. V

I will now describe briefly the modified construction of the tread-members and the attaching means shown in Figs. 3 and 4. The rails 30 are ,worn rails of usual conplates 23 except as to struction. The tread-members 31 are similar to the members 13 and each tread-member has a longitudinal channel 32 a longitudinal rib 33 and a downwardly extended member 34 analogous to the member 14 of the tread 13 but difi'ering therefrom in that the terminal part of the member 342 is bent inward to form a flange 35 engaging on the under side of the rail head. The connecting plates 36 are similar to the plates 20. Each plate 36 has a longitudinal flange 3'7 engaging the member 33 of the tread-members 31 and also has a shoulder 38 engaging on the under surface of the rail head. Bolts 39 securely connect the part-s in the same manner that similar parts of the preferred construction are connected. 7

It will be seen that the members 33 engage the members 37 of the plates 36, and the members 35 of the tread-members 31 engage the rail-heads to prevent upward movement of the rail-treads. v

Having fully described my invention what I claim as new and desire to secure by Letters Patent is In a track-rail, the combination of a body comprising a base anda laterally extended longitudinal member; an attaching plate engaging the laterally extended member of the body; a tread-member having a downwardly extended part, an internal longitudinal channel and an inwardly turned longitudinal flange; an attaching plate having a shoulder supporting the downwardlytextended parts of the tread member; and connecting devices connecting the attaching plates the tread member and the body as set forth. j r I In witness whereof I have hereunto signed my name at Springfield, Illinois, this 26th day of May, 1921.
